The scientists of The Laboratory for the Development of Substitute Materials (LDSM) have prepared for your examination Mirror City: A Phantom Experiment, a confusion of medical case study, living room slideshow, and amateur variety hour. Like the LDSM’s Theoretical Isolation: A Post-Atomic Experiment, which dealt simultaneously with physics, Shakespeare, and architecture, Mirror City conflates the city with the body, suggesting courses of treatment for three divergent case histories, each of whom present with personal sites of loss in the city of Chicago. The LDSM holds its odd theatrical mirror up to these anonymous subjects in order to sort out how it can still ache in places that no longer exist.
